A functional mild surfactant. Safe.
Laureth-9 is a nonionic surfactant based on lauryl alcohol with a chain of nine ethylene-oxide units. INCI: Laureth-9. In a formula it works as an emulsifier, solubilizer, and wetting agent: it helps bind oil and water and dissolve poorly soluble components. It is a functional component, not a skincare active. It is used in cleansers, emulsions, and technical formula bases. Pregnancy safety. In rinse-off and low-dose products, skin absorption is low and there is no evidence of harm with topical use. It can be used during pregnancy and lactation. Tolerance. Irritation potential depends on concentration and is low to moderate at usual levels. As with ethoxylated raw materials, the standard caveat about 1,4-dioxane removal in manufacturing applies.
